格式解析的json数组

I have a project where I have an encoded json array and need to format it so the elements inside the array print underneath each other like so in the index.php file.

this is my desired output for the elements inside the array, to be printed out underneath each other with a space for each new index

Desired output

here is my code so far:

allNames.php

<?php
// Get the string from the URL
$json = file_get_contents('http://5dd559d3ce4c300014402cb8.mockapi.io/onboard/posts');
printAll($json);
$array= array();
function printAll($json){
// Decode the JSON string into an object
$obj = json_decode($json,true);
$elementCount  = count($obj);
// In the case of this input, do key and array lookups to get the values
for($i=0; $i<$elementCount; $i++){

    #delimit based on added * after each attribute to ensure all elemets are added and not cut short
    $array[]=explode("*",$obj[$i]["id"]."*".$obj[$i]["createdAt"]."*".$obj[$i]["name"]
            ."*".$obj[$i]["avatar"]."*".$obj[$i]["jobDescription"]."*".$obj[$i]["userEmail"]."*"
            .$obj[$i]["userIpAddress"]."*".$obj[$i]["userAgent"]);
}

 echo json_encode($array);
}
?>

index.php

<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script type="text/javascript">

function ajax_post(){
     $.post("allNames.php", {
    }, function(data) {
      var returnedData = JSON.parse(data);
      $("#data").html(returnedData + "<br>");
    });
    };
</script>
</head>
<body>
<h2>Ajax Post to PHP and Get Return Data</h2>
<input name="myBtn" type="submit" value="Check" onclick="ajax_post()"> <br><br>
<center> <p id="data" style="color:black"></p><br><br> </center>
</body>
</html>

    This formats the JSON for printing. It is a working example.

    The $dataToPrint variable holds everything you want to print from the data. It checks for empty data, also does not print a separator if no data was outputted. It is pretty straight forward, it loops through everything.

    If you dont want to limit what is printed, just remove the $dataToPrint variable and the array_search(... condition and just print it instead.

    index:

    <html>
<head>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
    <script type="text/javascript">

        function ajax_post(){
            $.post("allNames.php", {
            }, function(data) {
                // var returnedData = JSON.parse(data);
                $("#data").html(data);
            });
        };
    </script>
</head>
<body>
<h2>Ajax Post to PHP and Get Return Data</h2>
<input name="myBtn" type="submit" value="Check" onclick="ajax_post()"> <br><br>
<center> <p id="data" style="color:black"></p><br><br> </center>
</body>
</html>

    allNames:

    <?php
// Get the string from the URL
$json = file_get_contents('http://5dd559d3ce4c300014402cb8.mockapi.io/onboard/posts');
$decodedJson = json_decode( $json, TRUE );
$dataToPrint = array(
    'id',
    'createdAt',
    'name',
    'avatar',
    'jobDescription'
);
$returningString = "";
foreach ( $decodedJson as $dataToDisplay ) {
    if ( is_array( $dataToDisplay ) && ! empty( $dataToDisplay ) ) {
        $printSeparator = FALSE;
        foreach ( $dataToDisplay as $key => $value ) {
            if ( array_search( $key, $dataToPrint ) !== FALSE ) {
                $printSeparator = $printSeparator || TRUE;
                $returningString .= "{$key}: {$value} <br/>";
            }
        }
        // Printed all from current, adding a HR or extra line break. Change as desired
        if ( $printSeparator ) {
            $returningString .= "<hr>";
        }
    }
}

echo $returningString;
